NOTE: When resetting the control to original factory defaults all control settings will be overwritten and will no longer exist. TOTAL CLEAR STARTED Release buttons and Please Wait ALERT Do not turn off power to control until all Startup settings have been made. Otherwise, the next power-up will be set to many Startup factory settings that might not fit your application. BMC and BMC-6X Installation and Operation Manual OPERATING SETTINGS PROGRAM CHANGE SETTINGS RUNPROGRAM To be able to change the BMC settings the Program/Run Switch must be set to Program. The switch is located under the Enclosure Wiring Cover for security. The Enclosure Wiring Cover can be securely closed using a lock. SEASON Winter, Summer Default: Winter Button: MENU/Season • The BMC will turn all boiler relays off when it is in Summer setting. However, a DHW call will bring boilers back on if needed. The Message Display Line will display Summer to show status. BACK SAVE ------------- SEASON -------------- Winter Summer ALERT • When in Winter, the BMC will activate the Sys relay whenever the Outdoor temperature DO NOT turn power off to the (OD) falls to or below the Outdoor Cutoff setting. In addition, it will begin heating whenever the System temperature (SYS) falls below the Set Point Temperature. The BMC when heating season is over. If you do so, the battery Message Display Line will not display any season information when in Winter. • When the heating season is over, it is a good practice to switch the BMC to Summer will run down and will have to be replaced. Instead, switch to setting. This will allow DHW calls to operate the boilers when needed. Summer. SET POINT (NOT ADJUSTABLE IN EMS MODE) Adjustable from 70.F/ 21.C to 250.F/ 121.C Default: 140.F/ 60.C Button: MENU/Set Point • The Set point is the temperature value the BMC will use to control the system. • It only be available when Set Point is selected as the Sensor Type. See page 14. • The BMC will increase, decrease or hold the modulation of the boilers to maintain the system temperature around the Set point. The amount of fluctuate around the set point depends on the Modulation Mode, System Settings, and Stage Settings. • If the EMS Mode was Enabled, the Set Point will be set by the EMS/BMS system and will be available to be read but not changed on the display. RESET RATIO Adjustable 1.00.OD : 4.00.Sys to 4.00.OD : 1.00.Sys Default: 1.00.OD : 1.00.Sys Button: MENU/Set Point • It's only be available when Reset is selected as the Sensor Type. See page 14. • The Reset Ratio determines how the System water temperature (SYS) will vary with Outside temperature (OD). With any of the ratios, the colder it becomes outside, the hotter the temperature of the system water. The ratios are adjustable from 1.00 (OD):4.00 (SYS) to 4.00 (OD):1.00 (SYS). (See Understanding Operation Concept on page 5) • With a 1.00 (OD):4.00 (SYS) ratio, the System water temperature (SYS) will increase rapidly as the outside temperature falls, hitting the maximum of 240°F at 24°F outside temperature. With a 4.00 (OD):1.00 (SYS) ratio, the System water temperature (SYS) will increase slowly as the outside temperature falls. Even at -30°F, the system water will only be 125°F, and at 24°F outside, the system water will be 112°F. Such a low BACK SAVE ------------ SET POINT ---------- 70 F [] --------- RESET RATIO ---------- 1.00 OD=4.00 Sys 1.00 OD=3.00 Sys 1.00 OD=2.00 Sys 1.00 OD=1.50 Sys 1.00 OD=1.25 Sys 1.00 OD=1.00 Sys 1.25 OD=1.00 Sys 1.50 OD=1.00 Sys 2.00 OD=1.00 Sys 3.00 OD=1.00 Sys 4.00 OD=1.00 Sys BACK SAVE Reset Ratio might be used with radiant floor heating applications. • With most baseboard heating applications, a 1.00 (OD):1.00 (SYS) setting is a good place to start. With a 1.00 (OD):1.00 (SYS) ratio, for every degree the outside temperature falls, the system water temperature is increased one degree. • If required: Adjust the RESET RATIO in cold weather. If the ambient building 1:4 1:1 130 Colder Warmer Water Temperature 120 temperatures are too cold in cold weather, move the ratio to a higher selection. That is, 110 4:1 if 1.00 (OD):1.00 (SYS) was initially selected, change the selection to 1.00 (OD):1.25 100 (SYS). If the building temperatures are too warm in cold weather, move the ratio to a lower selection. That is, if 1.00 (OD):1.00 (SYS) was initially selected, change the Outdoor Temperature 70 405060 selection to 1.25 (OD):1.00 (SYS). 17 BMC and BMC-6X Installation and Operation Manual OUTDOOR CUTOFF TEMPERATURE Adjustable Off, from 20.F/ to70.C - 100.F, On Default: 60.F/ 16.C Button: MENU/Set Point/Outdoor Cutoff in Set Point Button: MENU/Set Point/Offset/Outdoor Cutoff in Reset • If the outdoor sensor is installed, the Outdoor Cutoff screen will automatically appear after the temperature Set Point has been selected. • When the outdoor temperature falls to the adjustable Outdoor Cutoff temperature, the BMC will control and modulate boilers to hold the calculated temperature. • When the outdo...
